03/10/2021, 3:39 PMI have a lambda where I import ‘aws-xray-sdk’ but the dependency does not seem to be uploaded to AWS as the lambda throws “errorType”“Runtime.ImportModuleError”,“errorMessage”“Error: Cannot find module ‘aws-xray-sdk’… Shouldn’t Pulumi automatically handle this? I run npm i aws-xray-sdk before pulumi up ofc.

03/10/2021, 4:32 PMthat's not up to pulumi, is the dependency on your package.json?
make sure it's there, npm install as 'prod' dependency not a dev one

03/10/2021, 4:46 PMIt’s in my package.json yes under dependencies

03/10/2021, 5:02 PMthen the other thing I can think of is that pulumi is not deploying your dependencies.
look if node_modules is in aws

03/10/2021, 5:05 PMit's also a bit of a weird library

Copy code
import AWSXRay from 'aws-xray-sdk-core';b

03/10/2021, 5:17 PMUsing ‘aws-xray-sdk-code’ results in the same problem. I can only see my __index.js in the Code source explorer, unless you are referring to another part of the AWS console

03/10/2021, 5:28 PMI am defining the lambda from a file, do I have to add the dependencies here explicitly?
breezy-apartment-46543
03/10/2021, 5:29 PM Copy code
const fn = new aws.lambda.Function('InfraLambda', {
code: new pulumi.asset.AssetArchive({
'__index.js': new pulumi.asset.FileAsset('./handler.js'),
}),
handler: '__index.handler',
runtime: aws.lambda.NodeJS12dXRuntime,
role: role.arn,
tracingConfig: {
mode: 'Active', // Enable X-ray
},
});d

or use webpack to pack only your 'prod' dependencies and then declare the result of the build as an asset

03/10/2021, 5:39 PMI am using a library that copies node_modules over to /build folder and I am using that as asset. but I am using typescript so I need to transpile over the files
